1  Economy / Scam Accusations / Smartmixer has locked all of their ANN threads? on: February 21, 2020, 02:25:46 PM
Did anyone else notice this today? I'm not exactly sure when, but i think sometime after they stopped with their signature campaign, they locked all of their ANN threads.

On top of that, it seems that their website is becoming increasingly harder to access? Loading over clearnet doesn't work at all for me, and over tor it's about a 1/10 chance of the site actually loading.

Can Smartmixer themselves perhaps shed some light why they locked their ANN threads? Are you closing down? Have they done this before in times of maintenance (Am I missing something here?)

Anyway, a bit premature maybe, but let this thread perhaps serve as a secondary ANN where people can posts complaints/stuff they would otherwise normally post in their ANN thread.
Will delete if there's an explanation i missed / ANN gets unlocked.

Edit: As opposed to 504 errors earlier on, (Signs of ddos?) I now get 403 & 502 errors (Time to worry maybe?).
2  Economy / Service Discussion / Nexo - "Earn 8% dividend a year with no risks" on: June 30, 2019, 12:58:40 PM
See this article below which explains it:

So basically, you deposit your crypto, convert it to some shitty stable coin of them, and earn 8% interest on a yearly basis. They say they use them for loans or something? aaaand they're 1:1 backed.. ?

Hmm. Seems too good to be true other than the fact that your "gains" are measured in USD/EUR ofcourse, and not BTC. For now it seems that you can't earn interest on BTC (it says "Coming Soon".)

Is anyone using them? I've heard of them in the past for getting loans, but not this compound interest scheme. Might be interesting if it's legit.
3  Economy / Service Discussion / Bitdeer - Experiences? on: May 14, 2019, 07:02:02 PM
So this forum ad attracted my attention - it seems to offer real(?) mining plans?

Let's take a look at one of their plans;

180DAYS: 50 TH/s - 644$ - ($0.0716/T/Day) v Electricity: ($0.0970/T/Day)

~~0.1$ per TH/s = 5$ in electricity a day.

Gives ~15$ a day. (15*180=2700$)

2700te$ - 900E$ - 644Contract$ = 1156$.

1156/644 = ~80% ROE in half a year.
Are my calculations off? Is this site legit? (I assume so?) (I know that this does not take into account changes in difficulty, - but even with x rise, ROE would still be quite high..)
Why are they selling these contracts when keeping them themselves will benefit them far greater?

Or has this just become really attractive due to the rise of BTC? If so, does anyone know what the ROE% was before the sudden jump, it seems that they've been around for quite a bit looking at their previous rounds?

Just wondering if anyone has ever used them here.
4  Economy / Scam Accusations / Yobit Scam Accusation megathread. "Normal" modus operandi or shady practices? on: April 21, 2019, 11:38:38 AM
Let's have a healthy discussion as to why Yobit is/might be a shady exchange, and whether or not the promoters of said service should face any repercussions for the damages they do against customers who are unknown to Yobit's business practices. (Which is to squeeze as much money out of every customer possible.). Or if this is completely healthy, and everyone just has to do their own due diligence before using them.

Table of Contents:
I. Prologue.
II. List of various accusations against yobit. (Cannot be effectively proven, as we only have other people's accusations.)
III. Yobit selectively scamming users and freezing withdrawals. (Cannot be effectively proven, as we only have other people's accusations.)
IV. Yobit' site owners orchestrating pump & dumps.
V. Yobit's InvestmentBox .
VI Yobit's ticker ignorance/fraud.

[2] / (?)
[3] / (?)
[4] /

I. For those who don't know about yobit, they're a russian exchange[1], with various features which i think are quite controversial. They've been investigated for fraud in the past[2]. And have unknown owners. Although it is rumored that the actual owner was arrested on fraud charges[3]. It's unclear to me whether or not this is actually true though(?).

I might have a wrong view of certain business practices conducted at Yobit. If my accusations against them are false/ungrounded, please feel free to refute them.

II. This is pretty shocking. Over the years Yobit garnered hundreds of scam accusations, most of which have gone unanswered despite them having a BTT account. I haven't seen this number of scam accusations against any other exchange.

Just a few examples;  HOW YOBIT SCAMMED ME YOBIT SCAMMED ME 15.20780976 ETHEREUM YOBIT Scam Exchange Yobit scam ? Trade lost money Yobit SCAM - SYSCOIN withdrawal 1000+ ETH blocked: won't explain or resolve YOBIT scam - class action law suit YoBit seems wants to steal my money. Are they scammed? Scam market and Yobit.Net Scamming My Deposit

I'm kind of reluctant to show these as proof that yobit is a shady exchange, or scamming customers, as i don't know the ins and outs of each case..
However it is obvious that with yobit there's far more users complaining that they can't withdraw coins/their wallets have been frozen.

Some accusations, again.
Please unfreeze my YoBit account
Support tickets about NewYorkcoins should be directed to Yobit
yobit about to take off ?
WARNING YObit is a scam (User was able to login but had no support offered whatsoever.)
You can google far more examples of users not getting answers to their tickets, and thinking that they've lost their funds.

Now onto the observable questionable behavior:

IV. This one is quite obvious, and they're not shy from hiding it.

What they used to do is just call it a pump and dump, and  add a timer as to when they were going to "release" it (the pump). It was announced on all of their social media, "Pump and dump in X hours"[4]

It's unclear to me whether they still do this. (but don't worry, they replaced it with an instrument just as bad!)

So, after a boatload of criticism, i guess they changed it to "New ICO in X hours, (what's now a new "IEO"), so that it isn't really market manipulation anymore. (I'm guessing?)

They're still doing this as of today. You can see the countdown timer here.

Basically, they launch a non-existing project, and users can buy their sack of shit, hoping an even bigger fool will buy it from a higher price from them. I guess one could argue that this isn't against any laws, but it sure as hell is shady. And perhaps it is actually quite unethical to serve your customers a literal pile of dogshit with atleast some of them not knowing that what is on the menu is not edible..

They are conducting IEO for coins that do not exist - it's not a project. They make a paid "SHROOM" let's say, and that's it, new coin added. It's to generate profit for those who get in early - a kind of gambling game. It can be profitable or very taxing. I guess nothing wrong with that and up to each use to play their part or avoid it.
From someone who participated in them.

V. Their InvestBox. despite them stating the obvious;
Invest your free coins to InvestBox! Itís a tool for devs to promote their coins. Itís NOT Pyramid/HYIP, all payments are made from special fund.
InvestBoxes can change status from Active to ęNo coinsĽ, but you can close your investment any time, itís 100% safe.
If it's not a ponzi, (which, well, it really does have all the looks of it.), it for sure is a nice way to get more people into a shitcoin, of which the dev can then just dump all the coins of slowly to 1 sat. I believe this is what has been happening, and is the entire purpose of the "InvestBox".

Take a look at the "MOON" and "URANIX" investment plans, and it becomes fairly obvious.

Again, as i see it, this is just another way for yobit and shady coin developers to squeeze some more money out of ignorant/new traders.

VI. Yobit's ticker ignorance, or plain fraud? I'm not sure.

There are a couple articles about this explaining it, but basically it went like this. Yobit (or was it a third-party? No one knows...) created a shitcoin called Boat's n Boobs', and listed it as BNB.
through washtrading they kept the price ~x% under the actual marketprice BNB (Binance Coin) was trading at, and defrauded investors who thought they were buying actual BNB coins.

Code: (
1. Yobit take an established coin Omise_Go (OMG).
2. They then quietly create their own, useless coin, entitled OMGame.
3. Listing OMGame on their market using the ticker (OMG) at a handful of Satoshi cheaper than current market price they drive up hype for discount purchases (no note of OMGame is made to the consumer on the trading screen).
4. Volume is artificially kept high thanks to exchange wash-trading.
5. When people grow wise to the scam, Yobit delete the coin, leaving traders out of pocket unable to sell elsewhere.
6. Support emails in return claim that the coin was a 3rd party technology that no longer met the exchange's T&C and Yobit is not liable for remuneration.

The coin got "delisted" after some controversy.

Some articles/ reddit threads; [5] [6] [7] [8]

Now there are multiple questions to answer, the first one being as to what extend this sort of behavior is fraudulent, (If fraudulent at all, you decide.), and if it is, to what extent the promoters of Yobit are complicit in this.

People who promote ponzi schemes in Gambling threads, or advertise pump&dump groups are usually tagged/ ushered away rather quickly. If Yobit was proven to also engage in that behavior, wouldn't wearing their signature be essentially the same as promoting a ponzi/pump&dump scheme? (I don't know..)
5  Other / Meta / Excessively meriting a mediocre post - rules? on: April 07, 2019, 01:37:57 PM
See link;

I'm not sure what to think about this; is this abuse, or do the rules of free market and free choice apply here? The post doesn't look exceptionally good to me, especially since "better" (imo) answers had already been given.. (although perhaps Taki sees this differently..?)

Is this sort of behavior generally frowned upon, or is this perfectly fine?

Just wondering.
6  Economy / Currency exchange / [H] PP [W] BTC 1:1 Preev Rate. on: February 08, 2019, 02:38:45 PM
As title states, i'm looking to continously buy Bitcoin for paypal.
Rates will be 1:1 Preev.

Will update below with the amounts needed.

Currently looking to exchange: 200$ into BTC.

PM me if you're interested in dealing. Will/can go first with trusted members.
7  Economy / Services / Looking for someone who can program a small bot. on: January 01, 2019, 10:19:39 PM
I'm looking for someone who can program a small bot that automates a couple of things. (Modifying buy/sell orders, and checking if they're the closest match for the buyer/seller mostly.)

Most will probably be possible to do through an api that is provided by the service itself, although i'm afraid that you can't fetch certain orders. i'm not sure how much i should ask for this.

If you're interested in coding this, please PM me so i can go into detail about what's needed to be done, what service this is about and more specifications etc. and how much is a fair price for this.

8  Economy / Service Discussion / Binance's partnership with Chainanalysis to detect "Dirty" Coins.. on: December 04, 2018, 07:11:50 PM
So i recently discovered that Binance partnered with to detect transactions that could be coming from people whom launder money, fund terrorist organisations et al.

Does anyone know what the impact of this will be/has been (Has anyone been affected yet?)? Will coins send from a mixer to binance now require KYC (since they're untraceable = will probably get flagged??)?
Seems like the entire nature/reason of why crypto exists in the first place is silently being destroyed.  Undecided

I've never send coins from any mixer to binance, but i would be really reluctant to do so now, especially with unverified accounts...? The stuff that Polo/Bittrex pulled is still fresh in my mind.
This to me, seems like quite a big deal, but i have barely heard anything about this, or what it actually implies for the average user that's taking decent care of his privacy/trying to preserve anonimity...  Huh

9  Bitcoin / Development & Technical Discussion / What's going wrong here? Different privkeys from same XPRV. on: October 26, 2018, 12:12:13 PM

I start with generating an bip32 xprv from


m/44'/0'/0'/0/0 1Bc7RvUdCSHEZmyXkdwTe1JYEFLdd3ebvw 024d27c803e9cb8092021bb74643e188233e0985be5b7130e6b0966dce6458d4f2 KxXviT8QiwyeRT4KP2cQjjSMPSQKTEhsGvGdQtGoxK4sRQZTsbLj

From WIF compressed to HEX;
(Gives the following ETH adress )

I use the xpriv key in ethereumjs-wallet -

var hdkey = require('ethereumjs-wallet/hdkey');

var extPrivKey = 'xprvA1spA8iHkXqJwZHPeiEFDUkzmqgnF4LRLzDrioV98peEs2ykDutTjunz1H1jdiaPjMWG8ae6PornnWoDAZfw15xxkxqk4tJoa5Tn4yZJ1x4';

var hdwallet = hdkey.fromExtendedKey(extPrivKey);
var wallet = hdwallet.getWallet();
var address = wallet.getAddress();
var privatekey = wallet.getPrivateKey();
console.log(`Address: 0x${address.toString('hex')}`);
console.log(`PrivateKey: ${privatekey.toString('hex')}`);[/size]
Code used for generation of m/44'/0'/0'/0/0 (?) - (Is this correct? it should generate the same index=0 as above tool, right?)

Address: 0x03b82ba80f68502ee1f73e53a42175a89e718b66
PrivateKey: e174a4f2bc96cf67342c1bab1bfffa283c7a98cd08c61d6e829cdf683c13a844

Why are they different? - Am i missing something in their respective derivation methods?

This might not be the right section. Please move if it's not the appropriate section.
10  Other / Meta / Obvious fake bumping, but there's no proof. What to do? on: October 16, 2018, 06:07:52 PM
I strongly believe/suspect that there are multiple "exchanges" in the Service Announcements board which pay people to bump their threads.

Most noticeably;

(This exchange also uses SMM panels to boost their following on twitter et al. Proof;,, click one of the eggs that retweeted their stuff, you'll see the accounts have since been blocked.)

And is overall just extremely shady, they have no users/traffic data but more volume than the likes of Cryptopia, but i won't go into that now.

This entire site is just a ticking bomb waiting to go off.

What exactly can be done against this w/out concrete proof of them doing it? I know that there are some rules to prevent paid bumping, but how exactly is this usually proven?

11  Other / Meta / Why has this topic been removed? on: October 13, 2018, 08:06:02 AM
So i just woke up and saw that this topic abotu MIXERCOIN has been deleted all of a sudden.

I can't really fathom why, since the topic was quite informative, not spammy at all,  and really showed the utter ignorance of

Could the moderator who deleted it give their reasoning behind doing so?

EDIT: The modlog,, states the following;

Remove topic: New service of mixing BTC MIXERCOIN.CO in topic #5046279 by member #2424570

Does this mean that the OP deleted the topic, or that a mod trashed it and OP's ## is given as the one who deleted it because he is the topic starter? I'm not exactly an expert on how this modlog works..

(I'm pretty sure however that you can't delete topics in SA?)
12  Economy / Service Discussion / Has anyone ever used Copay to buy Amazon GC? on: September 21, 2018, 11:26:40 AM
I was looking for an easy way to buy products on Amazon with bitcoin.

As they don't accept bitcoins directly i soon found the likes of, but the reviews people have given this site and others that function the same way (Giftcards that people spend on your products are often carded/product never arrives/et al) didn't particularly satisfy me.

Copay however offers to sell you *legit* Amazon gifcards, at a 1:1 ratio, with no KYC/third parties required whatsoever - correct?

You can purchase Gift Card value in penny increments between $1.00 and $500.00.
1-500$ a day. Seems OK. what exactly are the fees on this is what i'm also pretty curious about..

The blogpost is pretty dated - 2016, so i'm wondering how accurate this still is.

Especially with sites like no longer offering Amazon GC (for bitcoin), because (i believe) they got restricted by Amazon from doing so. Why has this not happend to Copay & co? They offer the exact same service as far as i can see.

13  Bitcoin / Project Development / Would there be a market/interest for such a service? on: August 25, 2018, 01:04:51 PM
I'm thinking (Or rather fantasizing Roll Eyes) of creating a service where you could exchange bitcoin -> most altcoins & vice versa. Now i know that this market is very saturated, ( &

But i think that there is still a place for such a service, where there is more attention to lower fees, more accepted/tradeable coins, and more privacy/anonimity.

I was wondering what the community here thinks about the currently already existing instant exchanges such as Shapeshift & Changelly. If you use them, are you content with them? Are there things you wish that were different about them/are you missing features when using them?

I'm really just testing the waters here, i'd love to hear your opinions.
14  Other / Meta / Make links posted by Newbies unclickable. on: August 13, 2018, 10:21:53 AM
As the title suggests. I've spotted multiple newbies today alone spreading phishy links/straight malware/ self-advertising their shitty sites.

Simply making their links unclickable like you did with their signatures until they're Member would reduce all this spam, and might protect gullible users against these links before mods have a chance to remove them.

(I think this will also partially destroy the autobuy scams, as it's mostly Jr members/Newbies opening these topics with their fake links.)

EDIT: After thinking a bit deeper about this, i'm not entirely sure if these cons outweigh the pros (Since there are said newbies that make constructive posts using links, though that's the minority for sure..)
15  Economy / Digital goods / Are these DigitalOcean coupons actually legit? on: April 30, 2018, 12:43:07 PM
I am seeing alot of these 50$ DigitalOcean coupons for a very cheap price (1.5$ - 5$), which doesn't really make any sense to me.

I've tried asking a vendor if these are actually legit, but haven't really received an answer yet.

Has anyone ever bought these, and if so, what were the requirements for activating them on DigitalOcean? Is this actually allowed by DigitalOcean or are these sellers abusing some sort of giveaway code?

I'm tempted to buy a couple of these, but not if they're breaking DO's TOS/abusing something.

(Is this the right section for a thread like this? If not, please suggest where to move it to.)
16  Economy / Service Discussion / Where to buy laptops/PC's with BTC? on: April 24, 2018, 07:17:16 PM
I'm looking for suggestions as to where i can easily buy laptops with cryptocurrencies (preferably Bitcoin).

I've found this site,, but i'm not too sure how legit it is.

Anyone that has ever used them before? Alot of the products listed there redirect to a dead link, or are no longer available.
17  Economy / Services / Looking for developer on: April 11, 2018, 01:41:52 PM
I'm looking for a developer who has a good knowledge of configuring orderbooks for exchanges ( chaining them with Mysql databases, configuring down / up %% etc), aswell as displaying them correctly on (preferably) something like AMCharts.

I already have most of the code/infrastructure in place, the only thing that you'll need to do is configure it correctly.

If you think you can do this, please PM me, and we can figure a price etc. I can put money in escrow if that's something you'd want.
18  Economy / Services / Looking for someone to set up a script for me. on: March 24, 2018, 08:21:25 PM
As title states, i'm looking for someone to set up a script for me on my linux server.

It's primarily based on php, but it might be good to know how node.js / bitcoind works. Note that there's nothing to code, it's simply installing a script with some instructions in a ubuntu environment.

Please PM me if you think you can do the job, and give me your price.

Can pay upfront if you're trustworthy, it's not really a big deal.

//Closed, currently in talks with someone.
19  Other / Meta / Bitcointalk slow or just me? on: March 20, 2018, 03:51:02 PM
Bitcointalk currently loads extremely slow for me. Anyone else encountering this?

Whenever i use a third party to check the response time, it's usually ~300ms.

That can't be normal right?

This topic for example, with only 39 replies took me 10-15 seconds to load..?

Any fix to this? It's quite annoying when you're just scrolling/reading through threads.
20  Economy / Service Discussion / Simple question about coinpayments/Bitpay. on: March 10, 2018, 12:13:49 PM

If i were to use coinpayments for my business, would i be able to instantly liquidate the funds once they are confirmed by coinpayments to fiat, or do i then need to withdraw them to coinbase etc.
How does it exactly work? Anyone that has any experiences with this?
